ubifs: fix memory corruption in super.c

2016-04-22T09:48:17Z

In list "super_blocks" ubifs collects allocated super_block structs. U-Boot frees on unmount the allocated struct, so the pointer stored in this list is free after the umount. On a new ubifs mount, the new allocated super_block struct get inserted into the super_blocks list ... which contains now a freed pointer, and the list_add_tail() corrupts the freed memory ... 2 solutions are possible: - remove the super_block from the super_blocks list on umount - as U-Boot does not use the super_blocks list ... remove it complete for U-Boot. Both solutions should not introduce problems for porting to newer linux version, so this patch removes the unused super_blocks list, as it saves code size and execution time.

dm: blk: Rename get_device_and_partition()

2016-03-14T21:34:50Z

Rename this function to blk_get_device_part_str(). This is a better name because it makes it clear that the function returns a block device and parses a string. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Stephen Warren

dm: Drop the block_dev_desc_t typedef

2016-03-14T21:34:50Z

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long and causes 80-column violations, rename it to struct blk_desc. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Stephen Warren

bug.h: move BUILD_BUG_* defines to include/linux/bug.h

2016-01-25T15:39:59Z

BUILD_BUG_* macros have been defined in several headers. It would be nice to collect them in include/linux/bug.h like Linux. This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot. I'd like to postpone it until the root cause (the "error()" macro in include/common.h causes the name conflict with "__attribute__((error()))") is fixed.

Add more SPDX-License-Identifier tags

Move malloc_cache_aligned() to its own header

2015-09-11T21:15:16Z

At present malloc.h is included everywhere since it recently was added to common.h in this commit: 4519668 mtd/nand/ubi: assortment of alignment fixes This seems wasteful and unnecessary. We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this. With the name memalign.h it fits nicely after malloc() in most cases. Signed-off-by: Simon Glass Acked-by: Marcel Ziswiler
